To all whom 4'it may concern:

Be it known that I, EDWIN H. BENNERS, a' citizen of the United States,residing in Elizabeth, county of Union Aand State ofl New Jerse haveinvented certain new and useful Si e Frames for Car- Trucks, of whichthe following is a s eciiication.

rl`his invention is a si e frame for car trucks, the 'same appertainingmore especially to frames of that class which, in the main, are cast inone piece.

An object of the invention. is to facilitate the operation of assemblingthe bolster relative to the side frames, and to retain the bolster inposition after it shall have been inserted `in said frames'.v

Am important advantage secured by my invention is that bolstersofdifferent weights and sizes may be readily placed in position andretained within truck side frames of a standard size.

The side'frame of this'invention is designed and proportioned throughoutits several elements with a view to reducing the weight to a minimum,While securin the strength required to withstand the loa and Ithe sideor end thrusts, an especially irnportant feature being the ability ofthe side frame to-resist distortion which would result in disalinementof the axle boxes.

Each* side lframe is, preferably, 'of that.

class wherein the frame is cast in one piece. As will presently appear,said frame comprises an. arched top memb r, a bottom member, columnsconnecting t e top and bottom members, and stay members inclined withrespect to the top and bottom'members, each of said members being ofchanneled form in cross section.

According to one embodiment of the invention, the columns are parallelto each other,r the space between said columns exceeding the width ofthe bolster which is to be used in connection "with the truck by in,sorting its end portions into the vertical openin which are formedbetween the. aforesaid columns. For retaining the bolster in position,itis provided on,its res sides with grooves, each roovel being orined byparallel flanges or r1 s, the latter being, preferably, inte ral withthe bolster. Cooperating with t e grooved .bolster-are guide `.from theframe and are attached to the'columns therei of, said members protrudingfrom the opl' ectiveV posing faces of said columns, and fitting inA thegrooves ofthe bolster. is preferred to insert the guide members in thecolumns, provided with a recess bounded on all of its sides by walls,the latter being engaged by the-edges ofone gui'demember in such manneras to effectively retain the guide member in position, although it ispreferred to fasten each guide member to a column by one or more bolts.V

From the foregoing it should be noted that a grooved bolster may haveits end portion inserted into the opening of the side frame below theguide members, thus easily introducing said bolster, after which thebolster`is raised into the required position. At this time, the guidemembers enter the grooves in the bolster, and they operate thereafter toretain the bolster against sidewise or endwise motion relative to theside frame, saidv bolster being free, however, t0 move yorlay verticallywithin said truck and within the limits determined by the usual s rings.la t e accompanying drawings, I have illustrated one practicalembodiment of the invention, but the construction'shown therein is to beunderstood as illustrative, only, and not as defining the limits of theinvention.

Fig. 6 is an inverted or bottom plan View of a partof the right hand to confine the present invention to a one piece frame,for the reason that certain features of said invention may be used inconnrection with built-up frames. As shown,

'said frame consists of` a top member, a, a bottom member, the columns,c, c', and the L inclined struts or brace members, al,

i fr The top member, a, is arched from end to end thereof, although theend portions of said top member are flattened .on their lower sides, asat a', for the reception of the ped-` estals or aXle boxes, one of whichis indicated lin part by the reference character B at the left handportion of Fig. 1. As is usual in section, see -Fi s. 2 and 3, and it ispreferred to provide sai top member, a, withdepending flanges, a3, fromwhich extend rentrant flan es, a.

T e bottom member, b, is of channeled and skeletonized cross `seet1on,as shown 1n Figs. 1l and 3. The member, b, is provided structurepossessin y, in the lower with upstanding side flanges, b', and'withintermediatel webs, b2, thus producing a the requisite strength with avdecrease in t e Weight of metal.

The columns, c, c', join the top member, a,

With the bottom member, b, and as shown, these columns are equidistantfrom the middle portion of the frame. Said columns are parallel to eachother, and they are of channeled form in cross section, see Fig. 5. Eachcolunm is shown as provided with side flanges, c2, and the middleportion of the column is provided with slots or openings, c3, which.tend to decrease the weightjof the metal.` The columns 0,-are joined attheir lower portions with the 'bottom member, b,

and the inclinedstruts, d, d', .whereas the upper portions of thecolumns are joined with they channeled top member, a. The struts d, d,extend from the end portions of the b Ottom member, b, to the endportions of .the arched top member, a, so as to join with or merge intosaid members, a, b. Each inclined member is provided with side ribs, d2,thus producingl a strut of channeled cross section, see Fig. .7 i l Cdesignates a spring plank which is'fitted part of the opening which isformed. in the side frame by and `between the columns, c, c', the topmember, a, and the bottom member, b. .This spring plank may be ofanyvusual or preferred construction, and it rests upon the flanges andwebs, b', b2, of the'bottom member.

At the end portions of the spring plank are the angle reinforcingplates, D, one of which is shown in section in Fig. 1. The verticalmember of this angle plate engages with the inner face of one of thecolumns, whereas the horizontal member of said angle plate rests uponthe bottom member, b. The

,angle plate isfastened in position by bolts, e,

4which are shown in dotted lines in Fig. 3, and in full lines in Fig. 5,said bolts passing through the vertical member ofthev angle plate andalso through suitable lugs, e',

which are provided on the column. Through the horizontal member of theangle plate,

passes a vertical bolt, f, the latter extending throu h a web of thebottom member, b, where y each angle plate, D, is held securely inposition..

.Y As is usual in the art, the set of springs, shown partly in Fig. 1and indicated by the reference character, E, 'is seated upon the springplank, C, and these springs coperate with a bolster, F, for the purposeof holding the latter normally 'in a. working position within the sideframe. Said bolster,`F,

tween the flanges, f2, on one side of the bolster and the correspondingflanges, f2, on the opposite sidel thereof. This proportion of thevertical opening in the frame, A., 'to the width of the bolster, F,fenables an-end portion of said bolster to be thrust into or through thelower part of the aforesaid vertical opening in the side frame, thesprings,

E, bemg temporarily out of place.

For the purpose of retaining the bolster against endwise displacement,and to guide said bolster in its vertical travel or play within theupper part of the aforesaid vertical opening, I employ4 thev G, one ofwhich is provide face of each vertical column, c, c', whereby said juide,member is ada ted to occupy one of the vertical grooves, f?, of thebolster.

The members, G, are arranged in corresponding positions at the upperportions of guide members, on the mner the columns, 0,0', and on theopposing faces thereof, said members being a short distance below thetop member, a. VThe guidemembers, G, are parallel to each other, andthey protrude from the opposing faces of the columns, whereby said guidemembers are fitted 'snu 1y in the grooves which are provided in t esides of the bolster, F.

Each'guide member, Gr, is preferably cast vin a single piece of metal,and it is furthermore preferred to inset each guide member in one ofsaid columns for the purpose of rigidly fastening the guide `member tothe column in a way to reclude displacement of said guide member fiomsaid column. As shown 1n Figs. 1 and 2, each column is provided with avertical recess,y h, which. is bound on four sides by the marginal wallsor shoulders, lb', the recess being closed in l all its portions,'except on 'the inner face ofl ons,

the column. rThe guide member, G, is re-` duced on one side so as toform the seat portion, g, which is bound by the shoulders, g, and thisseat portion is fitted snugly 1n the recess, L, of the column, wherebythe shoulders of the guide member engagey with the shoulders, it', -ofthe recess. The seat portion, g, of said guide member fits snugly in therecess, h, so that it cannot move in any direction therein, and when thebolster is in position so that the guide-member will en-4 gage with thegroove side of the bolster, said guide member is retained in positionwithin the recessed column. It is preferred, however, to fasten theguide member in position in the recessed part of the column, and forthis purpose l have shown each guide member as beingheld in position bya transverse bolt, I, which passes through appropriate openings, z',which are provided in the channeled column so as to open into therecess, it.,

From the preceding description, it will be understood that the guidemembers, Gr, are fastened in positions on the columns, c, c', prior tointroducing the bolster, F, into the vertical opening of the side frame.When suclrbolstcr is introduced, its grooved end portion passes int-othe aforesaid vertical opening below the guidemembers, Gr', after whichthe bolster, F, is raised, Duringthe elevation of the bolster the guidemembers, G, enter the grooves, f, thus bringing the guide members intocooperative relation to said bolster. The springs are novi7 inserted inposition between the ,spring plank and the underside of the bolster,and, if desired, proper spring seats are employed for engagement withsaid springs.

As shown in Figs. 2 and 3, the side frame is provided lwith brake-beamhangers, J, which are preferably cast integralY with the top member, a,and the vertical columns, rf, c. These hangers extend from one side ofthe frame, and to the lower portion of cach hanger is connected astirrup, y', by means of a bolt, j.
